But the real smoking gun is whether the Obama administration was warned in advance that al-Qaeda was planning an attack. A number of Israeli newspapers have suggested that Washington was warned as early as September 4 – a week earlier – that the environment in Benghazi was becoming increasingly hostile and anti-American, while in London the Foreign Office took the decision to withdraw all its consular staff from Benghazi two months before the murders. This decision was based on an intelligence assessment made by MI6 that al-Qaeda was openly operating in the area following a failed assassination attempt on Sir Dominic Asquith, Britain's ambassador to Libya, in June.

It is well known that British intelligence works closely with its counterpart in America, and if MI6 knew al-Qaeda was operating in the Benghazi region, then it is highly likely that the CIA did too.
